Patent number: 12189043Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.Type: GrantFiled: December 8, 2023Date of Patent: January 7, 2025Assignee: QUALCOMM IncorporatedInventors: Han Zhang, Ning Luo, Gengsheng Zhang, Bo Zheng, Yinghua Yang, Min Wang

Publication number: 20240337755Abstract: A Precise Positioning Engine (PPE) may use correction information to perform highly accurate Global Navigation Satellite Systems (GNSS) positioning. Transitioning between, or “swapping,” of a first correction information source (e.g., Real-Time Kinematic (RTK) base station) with a second correction information source may be handled using correction information from the first correction information source to update a first state of the PPE. The updated PPE can then be modified by initializing at least ambiguity values of the PPE state. Correction information from the second base can be used to further update the PPE to a second state without a time update at the PPE. By employing this process, embodiments can reduce sudden changes in position estimation due to correction information source swapping, which can often result in resetting of the PPE and a reduced user experience quality.Type: ApplicationFiled: April 7, 2022Publication date: October 10, 2024Inventors: Min WANG, Ning LUO, Yinghua YANG, James STEPHEN, Han ZHANG, Yuxiang PENG, Satya Swaroop YADATI, Anupam KUMAR

Publication number: 20230417855Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.Type: ApplicationFiled: June 28, 2022Publication date: December 28, 2023Inventors: Yuxiang PENG, Ning LUO, Bo ZHENG, Jingchao BAO, Min WANG, Gengsheng ZHANG, Yinghua YANG

Patent number: 11668840Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.Type: GrantFiled: August 20, 2020Date of Patent: June 6, 2023Assignee: QUALCOMM IncorporatedInventors: Min Wang, Mangesh Chansarkar, Ning Luo, Gengsheng Zhang, David Tuck, Bo Zheng, Yinghua Yang, Han Zhang
